" WILLIAM BOOTH, or ROCHDALE, COUNTY or LANCASTER, ENGLAND.

CORNET OR OTHER MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 316,519, dated April28, 1885.

Application filed Decemberfifi, 1884. (No model.) Patented in EnglandNovember 4, 188-2, No. 5,432, and in France December 1.

To aZZ whom it may concern.-

Be it known that I, WILLIAM Boorru, a subject of the Queen of GreatBritain, residing at Rochdale, in the county of Lancaster, England, haveinvented a certain new and useful Improvement in Musical Instruments,(for which I have obtained Letters Patent in Great Britain, No.5,432,bearing date the 14th day of November, 1882, and in France, No.152,432, bearing date the 4th day of December, 1882,) of which thefollowing is a specification.

My invention relates to improvements in brass and otherwind-instruments; and the object of my improvements is to prevent theaccumulation of moisture (caused by the breath of the performer) in theslides or tubes of the instrument.

In applying my inventiomto a cornet or other instrument I fit on themouth-pipe or other tube a case or water-chamber in which the moisturecollects. In the upper side of this case or chamber I make an opening oropenings communicating with the instrument to admit moisture, and in thelower side I make an opening for the escape of moisture. In this case Ifit a tubular or other shaped valve in which I form an opening oropenings corresponding with the openings in the top of the case to admitthe water, and I make an opening or openings in the valve whichcorrespond with the opening in the lower side of the case when the valveis moved to allow the water. to escape. The holes in the upper part ofthe valve remain open except when the valve is moved by the performer toallow the water to escape. The valve thus formed will allowed themoisture to escape while the instrument is being played.

By the use of my invention long solos may be played withoutinconvenience from the accumulation of moisture; and in order that myinvention may be fully understood and readily carried into effect, Iwill proceed to describe the accompanying sheet of drawings, referencebeing had to the figures and letters marked thereon.

Figure 1 represents a longitudinal section, on an enlarged scale, of anapparatus made according to my improvements. Fig. 2 is a section acrossthe middle; Fig. 3, an end view,and Fig. 4 aplan, of the same; and Fig.5 illustrates the mode of applying the apparatus to one of the tubes ofa wind-instrument.

a is the outer casing,which is secured to the mouth-pipe of the cornetor other instrument,and b b are the openings to admit moisture, whichcorrespond with similar openings in the valve 0.

d is the opening in the case a through which the moisture escapes whenthe valve 0 is moved, so as to cause. the opening 6 in the valve tocorrespond with the opening (1.

To the valve 0 is connected a disk, f, to which is fixed a projection,g, which, when pressed by the finger, turns the valve partly round,closes the openings 12 1), brings the opening 6 over the opening d,andallows the moisture to escape.

A spring, h, causes the valve to move back when it is released andcloses the lower and opens the upper openings.

A small vent-hole, a, is make in the case and one 0' in the valve, whichadmit air when the moisture escapes through (1.

Instead of employing a valve movable in a rotary direction I may use avalve movable longitudinally or other wise.

What I claim as my invention and desire to secure by Letters Patent ofthe United States, is

1. In apparatus for. preventing the accumulation of moisture inwind-instruments, the combination of an outer casing secured to theinstrument, and provided with an opening or openings communicating withthe said instrument, and an opening communicating with the atmosphere,with a movable valve provided with openings corresponding with the saidopenings in the outer casing, substantially as herein set forth,forthepurposes specified.
